ION CANNON
Once the Ion Cannon has been assembled according to the previous direc-
tions. We’ll need to find a suitable place to run the Ion Cannon project. Select
a location that is not near sensitive electronics components and has easy ac-
cess to power so that you don’t have to reach across the running unit to turn
off the power. You don’t want to accidentally lean on it when you want to turn
it off or you will be in for a big surprise!
Plug in your 12 VDC power supply power (unit draws about 350 mA) into the
power jack (J1) on the Ion Cannon circuit board. Now turn on the power sup-
ply. You may possibly hear a slight hissing noise from the tubes and see a
small purple “flame” on the end of each of the points inside the pipes. This is
indicating that ion flow is occurring! Imagine, at this point there are complex
chemical reactions taking place to create ozone and nitric oxide. Even more
important is the constant release of ions into the air which can be felt with your
hand as a fairly strong breeze coming from the tubes!
Hold your hand in front of the tubes and notice the air flow. It is pretty sur-
prising how much air is being moved by the ions and how cool it feels. Why
does it feel so cool? Well the ions certainly aren’t chilling the air! It does have
some relation to the air moving however. If you compared this ion-pushed air
to the air of a fan that moved the same amount of air, this system would seem
much cooler thanks to a common meteorological term called “Wind Chill Fac-
tor”. Yes it is the same weather phenomenon that we New Yorkers (up here in
Victor) have to deal with every time we step outside! “Wind Chill Factor” is de-
signed to let us know how cold it feels to your skin versus how cold it actually
is outside. It is related to a variety of factors such as wind speed, humidity,
and how hairy you are! The hair factor isn’t taken into account during TV fore-
casts very often however! Believe it or not, the hair and the rough surface of
your skin is important in wind chill because they keeps a very thin layer of air
close to your body that resists movement of the surrounding air. This makes
an insulating layer that rides along with you at all times. In fact it takes a sur-
prising amount of wind to break this layer, something in the order of 20 miles
per hour or more!
Because our Ion Generator is producing ionically charged air, its attraction to
your conductive skin barrels allow the breeze to pass through the insulating
layer with very little effort. This causes a much greater ‘wind chill effect’ than
what would otherwise occur at the same wind speed. The evaporating mois-
ture from your skin only heightens this cooling effect as the ions transport the
drier air to your skins surface. I personally feel this is why some days seem so
bone-chillingly cold when there is hardly any wind and the thermometer does-
n’t seem to agree with how it cold it ‘feels’. Days like this usually occur just be-
fore a strong snow storm. I think it has a lot to do with ionic flow in the atmos-
phere, not just the humidity levels!
